Application filed March 28, 192%.

To all whom it may concern Be it known that l, iJlI-EOM D. Bunsen. a citizen of the United States oi? America. and resident of Rockwell City. Calhoun County, Iowa, have invented a new and usetul Plow, of which the following is a specification.

The principal object of this invention is to provide an improved plow having a mold board movable longitudinally, laterally and vertically relative to the path of travel, so that it will scour thoroughly and soil, no matter how sticky in character, will not stick to it.

A further object of this invention is to provide improved means for mounting movable members of a mold board tor travelv whereby movement is produced longitudinally, laterally and alt-itudinallv.

This invention relates to and is an inn provement on the invention described and claimed in Letters Patent ot the Unit-ed States Number 1,283,650 granted to me November 5, 1918, to which reference hereby is made.

My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in the claims and illustrated by the accompanying drawing, in which- Figure 1 :is a. plan view and Figure 2 a side elevation of a plow embodying my im provements. Figure 3 is a vertica section substantially on the line 3 3 ot l iqurc 1. Figure 4 is a. plan view ot the elements shown in Figure Figure l is an elevation showing a number of the traveling rods and their connections Figure- (3 is a vertical section, on an enlarged scale, on the line 6-6 of Figure 5.

Figure 7 is a view similar to Figure 5. showing a modified form. Figure 8 is a. cross-section, on an enlarged scale, on the line 88 of Figure 7.

In the construction of the device as shown a share 10 and landside 11 are employed in the usual relation and are suitably connected with a beam (not shown) whereby draft is applied. A landside bracket 12 is fixed at its forward lower end to the forward end portion of the landside 11 by means of bolts extending through holes 13 in said bracket, and said bracket extends upwardly and rearwardly on an arc to a point between and elevated considerably relative to the rear portions or the land- Serial No. 702,051.

side and share 10. Associated with the bracket 12 is a curved bar 14 arranged beneath. spaced from and supported relative to said bracket as hereinafter set forth. and said bar is of less length than the ln'acket and terminates at both ends short of the ends of said bracket. A fieldside bracket 15 is arranged transversely and connected at its ends to the rear end portions of the share 10 and landside 11, and said bracket has at one end. adjacent the share 10, a hearing or support 1.5 for a spindle 16 which extends upwardly and forwardly therefrom in an inclined position. projecting through holes 17 in the curved bar 14 and bracket 12 and having at its upper end a head 18 contacting the outer surface oi the latter bracket. The upper portion of the spindle 16 is threaded and locknuts 19 are screwed thereon and engage respectively the lower surface of the bracket 12 and theoppositc Faces of the curved bar 14. A field side wheel 20 is rotatably mounted on the lower portion of the spindle 16 adjacent the support 15 and share 10, said wheel obviously being arranged in a plane inclined to the horizontal. Landside wheels 21. 92

are arranged for rotation between the upper or rear portions. and between the lower or forward portions, respectively. oi the, bracket 12 and curved bar 14. the wheel.- 21

being of considerablygreater diameter than the wheel 22 and of somewhat less diameter than the tieldside wheel F20. The wheels 21.

22 are pivoted on nut equipped bolts 23. 2

respectively. mounted through and connecting the bracket and bar 14. and said bolts, together with the locknuts 19. serve to support and maintain the curved bar relative to the bracket. An arched brace 25 is fixed at one end to the rear portion 01 the landside 11, adjacent one end of the bracket 15. extends upwardly and rearwardly and has its opposite end overlying the rear end of the landside bracket 19 and tixed there-' to by the bolt 92-. A shield 26 is mounted over the landside bracket 12 and suitably secured thereto and is of sutticient width to cover the wheels 21. 22. said shield being formed with a peripheral downwardly extending flange 27 projecting beyond and partially enclosing saidwheels.

A movable moldboard for the plow is provided by means of a plurality of rods 28 car-. ried at their lower ends by the fieldside pulley 20 and flexibly connected at their upper Q near.

ends and mounted for traveling: engagement with the peripheries of the wheels 2L Each rod 28 is formed at its lower end with a thickened portiorrQ-S having; a circular aperture 29 therein (Figure 6) hv which it is threaded on the rim 01"? the ieldsidc wheel. 20, which is of skeleton form. thus forming; a pivotal connection between said wheel and the rods. Thea-re are enough of the rods 28 substantiallvto occupy all ou the space oircumterentiallv of the wheel with their enlarged portions 28. and said rods spread out in something of a fan-shape wheel, and have their upper ends nnito ii separated and received within the danced shield 26. The upper end portions of the rods 28 are reduced in diameter. (it 528. and are pivotally connected hv means of i s 29 in endless form. llach linh 29 is Formed oi. an angle bar. as shown in section in ic'nro 6. and eachlink is formed at each end. n one of its flanges. with an aperture to receive the reduced portion 28" ot a rod. such linlrs being attached to each rod and extending in opposite directions to adiacent rods. wherelii) a flexible, endless connection is formed hetweenthe outer ends oi the rods. The links 29 are held in place on the rods 28 by means of pins or lrevs 30 moun ed through the roda or in anv other suitahle mannen The other flanges oi the ansle-hm- .links 29 are arranged outwardlv ot the endless connection thus termed. and in slidina contact with the, inner i ace oi the lance 270i the shield 26. The endless traveling moldhoard thus formed is adapted for travel ,on the respective wheels. the lower end being; carried hv the fieldsirle wheel 20 and the upper end by the landside heels 91 and 22. the reduced upper ends oil the rods heinc" adapted for travel on. the peripheries o'l said wheels as indicated in Figure 6.

In use soil disp aced from the l nr ow hv the share 10 will fell upon the inovahle moldhoard shown and doscrihod and. the irictional contact therewith will cause the i clined surface above said share to travel rearwardlv. lonsritudinallv oi the plow. and also upwardlv or altitudina lv. hecause o the upward inclination oi? the rear side oil the fieldside wheel 20. and also laterallv in passino: around the wheels. the rods 28 pass ing to the rear and then to the lei-t around the wheels and then torwarrll in sucoossion. This travelingmovement oi the moldhoard will discharge therefrom the nrrow turned thereon under the plowinsr action. and thus prevent the soil from sticlrinq thereto. and the relative movement o the individual rods. in such movement. ahsolute- 1y prevents the accumulat on of anv soil even inworkin in sruinho and insnres'a perfect scouring action. 7

In the form shown in Fisrures i" and 8 an addition is made to the traveling; noldhoard in the way of substantially triangular shields 8i. forming a connection between adjacent rods 28. The shields 31 are termed sepa of sheet metal or the lite, and each iallv covers and fills the space hetveen pair of adjacent rods. lllach shield St is formed at its upper end with an innal ere 'l orniciil otl' to ne or strip netal. embracing: an upper portion oi? a and at lower end with a similar c einl raci lower portion or said rod chove the enla ed part 28'. thus iornr ir a pivotal coin tion het 'een one long 'i o'l the shield and the rod The opposite lone? .rnarogin each shield 3i is.

termed with an integral proicct n tongue between its ends. overla iipinj upon a marginal portion of an adiacent shield. to iii-even. this maro'in oi the shield from niovinn: inwardly of the device. The shields 31 serve to term a rela ively unhrolren surface for the movable nioldhoard and to prevent the entrance of dirt to the space within the same.

l do desire to he understood as liinit inninvsel'f to the precise construction and q'enlent here shown and descrihed. as 'arions modifications "may be employed.
